Apple phones list a 'System Data' category under Settings > General > iPhone Storage that, combined with the iOS install itself, can consume nearly half the space on a 128GB iPhone.

There is no way to fully eliminate System Data, though it can be reduced through specific maintenance steps.

Amadeus breach exposes data of 92,000 Japan Airlines customers

Japan Airlines disclosed that unauthorized access to Amadeus's Passenger Service System, which handles reservations and check-in, occurred between August 2023 and September 2026 and exposed data on roughly 92,000 customers. For most, exposed details included reservation codes, names, flight dates, routes and travel class, while about 2,000 customers also had contact details, passport numbers, frequent flyer numbers and ticket information exposed. JAL said credit card numbers and passwords were not compromised and that Amadeus has since applied security fixes, with flight operations unaffected.

UN and Google launch System Data Commons to feed AI accurate global statistics

The United Nations unveiled the UN System Data Commons, a new platform built on Google's open-source Data Commons technology that lets people query UN statistics using plain-language questions and supports the Model Context Protocol so AI systems can pull data directly. It replaces the older UNData portal, which relied on manual browsing rather than conversational search. The announcement came alongside a UNICEF study showing leading chatbots answered development-data questions correctly only about 21% of the time.
